### Describe the usage question you have. Please include as many useful
details as possible.
I'm pretty sure of this but wanted a sanity test. Also, should
`literal(quiet_NAN) == literal(signaling_NAN)`? My intuition is "no".
Or...more concretely...should these test cases pass?
```
// This currently fails
EXPECT_EQ(literal(std::numeric_limits<double>::quiet_NaN()),
literal(std::numeric_limits<double>::quiet_NaN()));
// These currently pass
EXPECT_NE(literal(std::numeric_limits<double>::quiet_NaN()),
literal(std::numeric_limits<double>::signaling_NaN()));
EXPECT_NE(literal(std::numeric_limits<double>::quiet_NaN()),
literal(std::numeric_limits<float>::quiet_NaN()));
```
If the answer is "yes, those two expressions are equivalent" then I can fix
it in #15180 . I already have a fix but wanted to confirm my understanding.
